MOLD.

Specification of Letters Patent.

Patented Feb. 18, 1913.

Application filed February 9, 1912. Serial No. 676,617.

To all whom it may concern:

Be it known that I, CHARLES W. Mo- DANmL, a citizen of the. UnitedStates, residing at Memphis, in the. county of Shelby and State ofTennessee, have invented certain new and useful Improvements in Molds,of which the following is a specification, reference being had to theaccompanying drawings.

This invention comprehends certain new and useful improvements inmoldingapparatus and relates particularly to a mold for use in formingconcrete burial vaults, although it is to be understood that theinvention is not limited to this use.

The invention has for its primary object a simple, durable and efficientconstruction of molding device, theparts of which may be easily cast andotherwise fprmed and readily assembled for use and disassembled for thepurpose of removing the vault, or for other purposes, the invention alsohaving for one of its primary objects a simple construction of moldingapparatus, both the core and flask of which are so arranged that theymay be extended within certain limits or retracted, as required,-to formvaults of difierent sizes, or vaults with walls of varying thicknesses.I

' The invention has for a further object an improved construction ofmold, the core of which is provided with simple and efiicient latchdevices designed to temporarily hold together the sections of which themold is formed, whereby the core in its entirety will be a substantialand rigid structure, while at the same time it may be easily knockeddown and removed, when desired.

And the invention also aims to generallyimprove this class of devicesand to render them more useful and commercially desirable. Y

With these and other objects in view, as will more fully appear as thedescription proceeds, the invention consists in certain constructions,arrangements and combinations of the parts that I shall hereinafterfully describe and claim.

For a full, understanding of the invention, reference is to be hadto-thefollowing description and accompanying drawings in which, I

Figure 1 is a top plan view of a mold constructed in accordance with myinvention. Fig. 2 is a sectional view thereof on the broken line 2-2, ofFig. 1. Fig. 3

(Sheet 2) is a transverse sectional-view on the line 3- -3, of Fig. 1.Fig. 4 is a similar view of the core on the line 4-4, of

in the accompanying drawings by like ref-- erence characters.

The flask A- of my improved mold embodies sides 1 and ends 2, as bestillustrated in Fig. 1. Thesides 1 are each formed at one end w1th upperand lowerlongitudinall extending slots 3 and are interiorly thic enedand preferably rounded at the opposlte end, as at 4. The end 4 of oneside is arranged diagonally in relationto the other side. The ends 2 ofthe flask A are correspondingly slotted at one end, as indicated at 5,and interiorly thickened at the opposite end, as indicated at 6, theslotted and interiorly thickened ends of the parts 2 being also arrangedin diagonal relation to each other, as best illustrated in Fig. 1. Setscrews 7 work inwardly in the thickened ends 4 and 6 at the corners ofthe flask and are received in the adjoining slots 3 and 5 of the partsheretofore described, the parts being so proportioned and arranged thatthey may be extended or moved inwardly over each other to a limiteddegree and yet to the'maximum required in a device of this character,the parts being securely held in adjusted position 'by tightening up theset screws 7. Preferably the outer faces of the sides are formed withinset anels 8 designed to produce correspon ing intaglio panels .in thebody portion of, the. vault formed therebyv and the ends 2 of the flaskA are correspondingly formed with panels 9.

The coreof the mold, is indicated .B as a whole, and includes angularcorner sections 10, each of which forms a part of one side and of oneend of the core. The'core, as will be evident by the accompanyingdrawings, is frame-like in character and 1s constructed of four mainparts or castings that are held in at their adjoining ends b flangedspacingmembers 11, one of 'whic is shown in detail in Fig. 5.' Preferablthese spacing members are downwardi; tapered, as indicated in Figs.- 4and 5, and

are adapted to fit within vertical flanges 12 formed on the sections 10at the opposite ends thereof. In order to secure the spacing membersinplace, hand-operated latches 13 are provided. Each latch 13 is formed atone side with an aperture 14 by which it is pivotally connected to theouter face of one of the flanges 12, each latch being fur ther formedwith a handle 15 and with spaced lugs 16 that, in the operative positionof the latch, are designed to straddle the outer faces of the flange 12to which the latch is connected and the adjoining inner wall of one sideof the corresponding spacing member 11. This is clearly indicated inFig.4 and also in Fig. 3. In order to assist in guiding the spacingmembers into their positions and to maintain them properly in place whenlocked by the latches 13, each spacing member is provided at its upperend with outstanding lugs or nibs 17 designed to fit within thedownwardly tapered recesses 18 that are formed at the juncture of theupper ends of the flanges 12 and the upper horizontal flanges 19 of thesections 10 (see Fig. 4).

The entire core B-,is in the present embodiment of 'the inventionsupported with its bottom flanges in spaced relation to the base-boardwhich is designed to support the flask A, by transversely extending bars20,

the ends of which extend over and rest detachably upon the upper edgesof the sides 1 of the flask, as at 21, the intermediate portions of.thebars being secured 'to the upper flanges 19 of the sect ons 10 of thecore B by bolts and nuts, as indicated at 22. By this means, the coremay be easily inserted in place with its parts in assembled relation toeach other.

From the foregoing description, in connection with the accompanyingdrawings,

, the operation of my improved molding apparatus will be apparent. Inthe practical use .of the device, the parts of the flask A ,are set upand adjusted, as required, ac

' cording to the particular size of burial vault to be molded, and thesections 10 of the core B are secured together by means of theintervening latches 13 and the spacing members 11, it being understoodthat spacing members of varying widths are to be employed according tothe particular size it is desired the core B shall have. After thesections 10 of the core B have been securely locked together with theirintermediate spacing members 11, by pressing downwardly upon the latches13, the entire core is set down into the flask A, it being-held insuspended position therein by the ends 21 of the bars 20 extending overthe upper, ed es of the sides 1. It is to be understood t at any of themethods ordinarily employed with molding apparatus of this character,may be employed with my improved molding apparatus. For instance, theconcrete may be poured into the flask A up to a predetermined level, thecore B may then be inserted in position, and the concrete then poured inaround the spaced walls of the flask and core to complete the bodyportion of the vault. Preferably, the flask B -is formed at its upperedge and on its exterior wall with a head 23 substantially rectangularin cross section, said bead being designed to form, in the completedarticle, an interior upwardly facing channel designed to receive the lidor cover of the vault. If desired, the cross bars 20 that are designedto support the core within the flask, are set in recesses 24 formed inthe upper edges of the sections 10.

It will thus be seen that I have provided a very simple and efiicientconstruction of molding apparatus, particularly designed for use informing the body portions of concrete burial vaults, and that the partsmay be easily assembled and very readily knocked down and disassembled,or adjusted, as the particular requirements of the case may demand.

While the accompanying drawings disclose what I believe to be thepreferred embodiment of my invention, it is to be understood that theinvention is not limited thereto, but that various changes may be made.in' the construction, arrangement and proportions of the parts withoutdepartin from the scope of the invention, as define in the appendedclaims.

7 What I claim is 1. A mold of the character described, including aflask, a core co-acting with said flask, the core being constructed ofangular sections, each of which is designed to constitute a portion ofone side and of one end of the core and the sections formed at theirends wit-h substantially vertical flanges, flange spacing membersadapted to fit be-- tween the ends of the sections to complete thecontinuity of the core, pivoted latches carried by the flanges of thesections and adapted to overlap the flanges of the spacing members,whereby to detachably connect the spacing members to the sections, thelatches each bein formed at one side with an apertured ear y which it ispivoted to a flange of a section and being also provided with laterallyspaced lugs extending at right-angles to the ear and adapted to clamptogether the said flangeand one of the flanges of the adjoining spacingmembers.

2. A mold of the character described, including a flask, a coreco-acting with said flask, the core being constructed in sections, eachof which is designed to constitute a portion of one side and of one endof the core and the sections formed at their ends with inturned flanges,said flanges diverging upward and outwardly, tapering flanged spacingmembers adapted to fit between the ends of the sections, pivoted latchescarried by. the flanges of the sections and adapted to overlap theflanges of the spacing members, whereby to detachably connect thespacing members to the sections, the latches being each formed at oneside with an apertured. ear by which it is pivoted to a flange of asection and" being also provided with laterally spaced lugs extending atright angles to the ear' and adapted to clamp together the said flangeand one of the flanges of the adjoining spacing members, each spacingmember being formed at its top with outstanding 15 lugs and the sectionsbeing formed with recesses for the reception of said lugs.

In testimony whereof I hereunto aflix my signature in the presence oftwo witnesses.

CHARLES. W. MoDAN-IEL.
